The Masterline K-Palm curves are new with a totally redesigned fit. These gloves have been re-engineered to fit better than ever. After prolonged use in the water, gloves will tend to loosen and become too large. The finger of the new gloves fit more snug and have to be pushed on. You will need to work each finger of the glove down to the base of your finger. These will stay tight and help prevent bunching and blisters. THese gloves are designed to be worn without glove liners.
